Elderly women with cervical cancer face double jeopardy. Not only does their advanced age decrease chances of survival, it also decreases the likelihood that they'll be given the most aggressive treatments for their disease, according to a study by researchers at Washington University School of Medicine in St. Louis.
Individuals with either calcium oxalate or calcium phosphate kidney stones should not take extra calcium on their own as suggested by previous research, but should check with their doctors to determine the dietary guidelines that work best for them, researchers at UT Southwestern Medical Center at Dallas have found.
The largest single collection of biosamples and data is now available for research on the genetic causes of kidney disease in type 1 diabetes.
The January 2005 issue of the Journal of the American Dietetic Association contains research articles including a study on the top dietary sources of caffeine and the use of dietary supplements for children with chronic diseases such as cystic fibrosis.
MDCT angiography can potentially help determine which patients with narrowed carotid arteries are at greater risk of having a stroke, a new study shows. This information could help identify which patients need surgery and which can be treated with less invasive procedures.
Women who have their breast cancers detected by physical examinations are at least twice as likely to undergo toxic treatments than those who have their cancer detected by mammography--regardless of the age of the woman, a new study shows.
Mice missing a specific protein from their brains react to stress differently. The genetically engineered mice develop an imbalance in a hormone involved in stress responses, and during stressful situations, they behave as if they are depressed. Genetic variations in the same protein may be a significant cause of human depression, according to researchers at Washington University School of Medicine in St. Louis.
People with a history of migraines and other headaches lasting at least four hours are more likely to report suffering from the chest pain doctors call angina than people who do not experience such headaches, a new University of North Carolina at Chapel Hill study concludes. That is especially true for those who also experience "aura" around the time of their headaches -- seeing what appear to be spots or lines before their eyes.
Can the toxicological effects of cigarette additives be measured? A new report concludes they can.
A new study says cancer surgery performed at a medical center designated by the National Cancer Institute (NCI) as a "center of excellence" is associated with less risk of death soon after surgery than if performed at a high-volume surgery center, but finds no difference in five-year survival rates.
Longer and more intense physical activity may help people maintain their cognitive skills as they age, according to a 10-year study of elderly men published in the December 28, 2004 issue of Neurology, the scientific journal of the American Academy of Neurology.
Both ibuprofen and acetaminophen are safe and effective for treating migraine headaches in children and adolescents, according to the American Academy of Neurology and the Child Neurology Society, whose new practice guideline is published in the December 28 issue of Neurology, the scientific journal of the American Academy of Neurology. The guideline has been endorsed by the American Academy of Pediatrics and the American Headache Society.
High levels of a blood protein called mannose-binding lectin (MBL) are associated with lower risk of heart attack, particularly among diabetics, report Saevardottir and colleagues. They suggest that measuring this protein in the bloodstream may help doctors decide if certain patients should receive additional treatments to decrease their heart attack risk, according to a study in the January 3rd issue of The Journal of Experimental Medicine.
The PLoS Medicine Debate for this month shows the pros and cons in the uses of biomedical enhancement technologies, which are developed for purposes other than treating diseases, such as improving our appearance and regulating our emotions.
In the premier open-access international medical journal, PLoS Medicine, a provocative research shows that injection of targeted nanoparticles, combined with magnetic resonance imaging, allows identification and detailed three dimensional placement of malignant lymph nodes.
In this issue of PLoS Medicine, a premier open-access international medical journal, an article provides information on the development of the Tropical Disease Initiative, a Web-based, community-wide effort where scientists from the public and private sectors join together to discover new treatments for diseases.
It's not often that an entire nation's genealogy and cancer records are available. But they are in Iceland, and have been used to determine how often cancers occur in families.
Research on the genome of the virus that causes severe acute respiratory syndrome (SARS) has revealed an unusual molecular structure that looks like a promising target for antiviral drugs. A team of scientists at the University of California, Santa Cruz, has determined the three-dimensional shape of this structure, an intricately twisted and folded segment of RNA. Their findings suggest that it may help the virus hijack the protein-building machinery of infected cells.
An inexpensive, non-narcotic medication has been identified as an important step in treating acute migraine headaches
For the first time, scientists have found that bacteria can use a Sonar-like system to spot other cells (either normal body cells or other bacteria) and target them for destruction. Reported in the December 24 issue of Science, this finding explains how some bacteria know when to produce a toxin that makes infection more severe. It may lead to the design of new toxin inhibitors.
As a result of a worldwide cooperative movement, the absolute driving ban for people with epilepsy (PWE) has been lifted in Japan. Since 1960, people who have epilepsy have been banned from driving in Japan. A December article in the journal Epilepsia outlines the efforts and procedures taken to reinstate driving rights to people with epilepsy, a restriction affecting many epilepsy patients throughout the world.
By alternating the flow of fluid through tiny plastic pipes, a team of mechanical engineers at New Jersey Institute of Technology (NJIT) has discovered a new and speedier way to mix liquids, which in turn will someday produce better and safer medications.
There is a desert in the heart of the South Pacific. Surrounding Easter Island is the purest and bluest seawater on Earth, almost empty of the microscopic phytoplankton at the base of the marine food web. French vessel L'Atalante recently completed a research cruise through this region, its day-to-day route guided by ocean colour satellites.
Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain.
Researchers at Dana-Farber Cancer Institute have compiled the first atlas showing the locations of crucial gene regulators, or switches that determine how different parts of the brain develop - and, in some cases, develop abnormally or malfunction.
